BioEra and Latency Timer adjustment
I received my board last week and sent it off to Jarek at BioEra so he could create a driver. He has what appears to be a working driver ready but noticed that the data is coming through in one second bursts rather than a continuous data stream. The bursts like this would appear to be problematic for neurofeedback. Jarek sent me a video of the his test running in processing, and it shows the bursts quite clearly. It does not look at all like the videos of your app that have been posted to the web.
Can I get a some clarification on this? Ia there a setting on the board or the 32bit chip that would enable a continuous data stream
Thanks

Changing the FTDI Latency Timer will fix this, see these two posts.

I'd love to know when the BioEra new version is available that supports OpenBCI. As we both use it for our neurofeedback work. Thanks so much for coordinating with Jarek like this. His tech support for BioEra is superb.

FYI, Brainbay new version is available as well,

A clarification for others reading this thread: Jarek was able to do that because he could adapt one of his existing internal BioEra USB serial driver modules to talk to the FTDI hardware device directly. This bypasses FTDI's own driver which has a Control Panel interface for adjusting the Latency Timer. So this is a great solution for BioEra users.
The rest of us talking with the OpenBCI dongle using other software, will have to continue using the FTDI driver. Since Jarek's BioEra and internal drivers are proprietary.
But it does open the possibility that there are other USB serial driver approaches out there, besides having to go with the manufacturer's driver. For example:
